山东莱州吴一村ZK01科学钻孔钻探施工技术

Drilling Technology for Scientific Drilling ZK01 in Shandong Province

摘要:

本文介绍了山东莱州吴一村地区ZK01钻孔的施工概况及所采用的关键技术。ZK01钻孔终孔孔深3266.06m,终孔孔径Φ98mm,采用了HXY-9型钻机等设备。针对施工中出现的超深孔施工，钻探机具配套困难及复杂地层施工等施工难点,详细阐述了国产HXY-9型钻机在施工中的不足,深孔钻杆柱的组合配套使用,复杂地层中LBM为主体的双聚泥浆体系的应用以及特制JS150/122绳索取心钻具的应用等关键技术。

Abstract:

This paper introduces the construction situation of scientific drilling ZK01 and the key technologies adopted, HXY9 type drilling rig and some other equipment are used and the final depth of ZK01 is 3266.06m with 98mm in diameter. According to the difficulties in super-deep hole construction, complex formation construction and drilling machines matching, the shortage of China-made HXY9 type drilling rig and the key technologies of the combined use of deep hole drill column, the application of double polymer mud system with LBM as main component in complex formation and the application of special JS150/122wire-line coring drill are elaborated in detail.
